The tithe was never about wages in the Bible.... ever.
It was about agricultural increase given by God and the returning of a portion of God's increase for His work to be accomplished.
Now people will jump in with their "Brother you fail to understand that it was an agrarian society" excuse.
In the whole of nearly 4000 years of biblical written history there is not one reference to the tithe having anything to do with wages. You'd think if God was talking about money then, over a span of 4000 years he'd find a way to mention that.
Also the very book (maybe chapter) where the tithe is instituted in the law there is also law given concerning lending money and usury.
So there was a monetary system in place and God said nothing about wages.
Nearly 4000 years passed and God said nothing of the tithe being on anyones wage.
Nearly 4000 years of written law and we have not one instance where a wage was tithed.
Jesus, when speaking of the tithe, again mention agricultural terms.
Malachi, when speaking of the tithe, speaks in agricultural terms.
And all they have to say is "Brother, you fail to understand that it was an agrarian society"
Also... to better understand what Malachi was talking about read my thread
here.
And... let it not be said that I ever even vaguely suggested anyone not pay a tenth. I think it is a great guideline to start with.
But it can be said that I said that to teach it as a law is disingenuous IMO.
